      Szafranska, Karolina; Kruse, Larissa D.; Holte, Christopher Florian; McCourt, Peter; Zapotoczny, Bartlomiej (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-13)
      The porosity of liver sinusoidal endothelial cells (LSEC) ensures bidirectional passive transport of lipoproteins, drugs and solutes between the liver capillaries and the liver parenchyma. This porosity is realized via fenestrations – transcellular pores with diameters in the range of 50–300 nm – typically grouped together in sieve plates. Aging and several liver disorders severely reduce LSEC ...

    • Dysregulated non-coding telomerase RNA component and associated exonuclease XRN1 in leucocytes from women developing preeclampsia-possible link to enhanced senescence 

      Lekva, Tove; Roland, M.C.P.; Estensen, M.E.; Norwitz, Errol R.; Tilburgs, T.; Henriksen, Tore; Bollerslev, Jens; Normann, K.R.; Magnus, P.; Olstad, Ole Kristoffer; Aukrust, Pål; Ueland, T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-05)
      Senescence in placenta/fetal membranes is a normal phenomenon linked to term parturition. However, excessive senescence which may be induced by telomere attrition, has been associated with preeclampsia (PE). We hypothesized that the telomerase complex in peripheral blood mononuclear cells (PBMC) and circulating telomere associated senescence markers would be dysregulated in women with PE. We measured ...
    • Cutoff criteria for the placebo response: a cluster and machine learning analysis of placebo analgesia. 

      Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)
      Computations of placebo effects are essential in randomized controlled trials (RCTs) for separating the specific effects of treatments from unspecific effects associated with the therapeutic intervention. Thus, the identification of placebo responders is important for testing the efficacy of treatments and drugs. The present study uses data from an experimental study on placebo analgesia to suggest ...
    • Facilitation of object encoding in infants by the observation of giving 

      Tatone, Denis; Hernik, Mikołaj; Csibra, Gergely (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-15)
      We propose that humans are prepared to interpret giving as a diagnostic cue of reciprocal–exchange relations from infancy. A prediction following from this hypothesis is that infants will represent the identity of an object they see being given, because this information is critical for evaluating potential future reciprocation. Across three looking-time experiments we tested whether the observation ...
    • Rapid Atlantification along the Fram Strait at the beginning of the 20th century 

      Tesi, Tommaso; Muschitiello, Francesco; Mollenhauer, Gesine; Miserocchi, Stefano; Langone, Leonardo; Ceccarelli, Chiara; Panieri, Giuliana; Chiggiato, Jacopo; Nogarotto, Alessio; Hefter, Jens; Ingrosso, Gianmarco; Giglio, Federico; Giordano, Patrizia; Capotondi, Lucilla (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-24)
      The recent expansion of Atlantic waters into the Arctic Ocean represents undisputable evidence of the rapid changes occurring in this region. Understanding the past variability of this “Atlantification” is thus crucial in providing a longer perspective on the modern Arctic changes. Here, we reconstruct the history of Atlantification along the eastern Fram Strait during the past 800 years using ...
    • Effects of rewarming with extracorporeal membrane oxygenation to restore oxygen transport and organ blood flow after hypothermic cardiac arrest in a porcine model 

      Nilsen, Jan Harald; Schanche, Torstein Lindahl; Valkov, Sergey; Mohyuddin, Rizwan; Håheim, Brage; Kondratyev, Timofey; Næsheim, Torvind; Sieck, Gary C.; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-23)
      We recently documented that cardiopulmonary resuscitation (CPR) generates the same level of cardiac output (CO) and mean arterial pressure (MAP) during both normothermia (38 °C) and hypothermia (27 °C). Furthermore, continuous CPR at 27 °C provides O2 delivery (ḊO2) to support aerobic metabolism throughout a 3-h period. The aim of the present study was to investigate the effects of extracorporeal ...

      Paulsen, Benedikte; Gran, Olga Vikhammer; Severinsen, Marianne T.; Hammerstrøm, Jens; Kristensen, Søren Risom; Cannegieter, Suzanne C.; Skille, Hanne; Tjønneland, Anne; Rosendaal, Frits; Overvad, Kim; Næss, Inger Anne; Hansen, John-Bjarne; Brækkan, Sigrid K. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-21)
      Smoking is a well-established risk factor for cancer, and cancer patients have a high risk of venous thromboembolism (VTE). Conflicting results have been reported on the association between smoking and risk of VTE, and the effect of smoking on VTE-risk in subjects with cancer is scarcely studied. We aimed to investigate the association between smoking and VTE in subjects with and without cancer in ...
